About Group no. of periodic table!
« on: January 20, 2005, 06:13:01 AM »
Is it the previous version of group no. (e.g. IA, IIA, IIIB, IVB...) now changed to 1 - 18?

IUPAC has now changed the periodic table so that the Group numberings will read fromm 1-18
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.

Is this new periodic table recognised world wide?
"Say you're in a [chemical] plant and there's a snake on the floor. What are you going to do? Call a consultant? Get a meeting together to talk about which color is the snake? Employees should do one thing: walk over there and you step on the friggin� snake." - Jean-Pierre Garnier, CEO of Glaxosmithkline, June 2006
